How to Combine Files into One PDF in Adobe Acrobat

Stack of file folders with text overlay "How to Combine Files into One PDF in Adobe Acrobat"

One of Adobe Acrobat’s most convenient features lets you combine files into one PDF. Best of all, the files don’t have to be other PDFs—you can combine nearly any file (e.g., Word, Excel, PowerPoint, or image) as long as you have the corresponding software on your computer.

This tutorial walks through all the steps to combine files. Plus, the bonus section at the end shows how to organize and delete pages after combining the files.

Important Note: The files you combine will be converted to the PDF format. So, files with interactive properties (such as Excel files) will be “flattened” to a text format. (However, the original file will not be affected.)

If you want to combine files without converting them to PDFs, please see “How to Create a PDF Portfolio in Adobe Acrobat” and “How to Insert Files into Existing PDFs in Adobe Acrobat.”

This tutorial is available as a YouTube video showing all the steps in real time.
